FAQ
My display is supposed to accept 4K60 4:4:4 signals but it does not work?
For most UHD TV set we tried, there are always extra configuration options to active in order to achieve
a 4K60 4:4:4 600MHz link. For ex, on samsung: in order to enable the 444 colorspace for 4k in Samsung
TV’s you must go to "settings" and "hdmi" and "UHD color" and enable it. Then also you must assign the
HDMI port1 as "PC" in the tools menu. Only after these two steps will 600MHz be accepted. Similar
activation tricks are required on most UHD TV’s. Additionally, most UHD TV’s only have specific ports
that are 600MHz capable.
I have a PC mode on my TV (or a PC monitor) what resolutions are supported for graphics mode?
All PC graphics mode within the 600MHz bandwidth are supported, including ultra-high resolution such
as WQSXGA, QUXGA, QFHD, WQUXGA, 4K, however HDCP conversion is only possible in SD/HD/FHD and
UHD modes.
What output resolution does the Linker support in HDTV mode?
All known SD, HD, Full HD and UHD formats are supported including: 480i50,480i60, 480p50, 480p60,
576p50, 576p60, 720p50, 720p60, 720p100, 720p120, 1080i25, 1080i30, 1080p24, 1080p25, 1080p30,
1080p48, 1080p50, 1080p60, 1080p72, 1080p75, 1080p96, 1440p50, 1440p60, 2160p24, 2160p25,
2160p30, 2160p50, 2160p60, 4K DCI (these are examples only, anything within the 600MHz bandwidth
is supported.)
What version of HDMI does the Linker work with? Do I need HDMI 1.3/1.4a/2.0a? Does it matter?
It does not matter. HDfury Linker works with any version of HDMI from 1.0 and up.
Do I need to set anything special in my HDMI source device to set the resolution correctly?
No. The HDfury Linker will be detected as 2160p60 4:4:4 capable device by your source and it will always
accept and process the highest quality stream from your source devices. There is no need to set the
HDMI source to any specific resolution.
Is there any latency (delay) introduced to the signal?
Virtually none. The latency added is in the order of a few pixel clocks only. Nothing noticeable at all.
What is the USB port for?
To provide power from the supplied USB power unit and for firmware upgrades when new (additional)
functions and enhancements are offered.
What about long HDMI cable runs? Can I expect issues?
For 600MHz users must use "high speed" cables, or 600MHz/18Gbps certified. For 4K30, 1080p or less
almost all cables are ok. HDfury Linker acts as a HDMI repeater device. So having a HDfury Linker in the
